HARVESTER.

SPECIFICATION forming part of Letters Patent No, 360,120, dated March29, 1887.

Application filed September 1, 1886. Serial No. 212,427.

To ctZZ whom it may concern.-

Be it known that I, Join: F. STEWARD, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in I-Iarveste1's,wl1ich arefully set forth in the following specification, reference being had tothe accompanying drawings, forming a part thereof.

Figure 1 is a perspective of a portion of a harvester-frame and thedrivewheel axle and the raising and lowering pinions thereon, containingmy invention, the direction of view being from the rear outer corner.Fig. 2 is a horizontal section through the drivewheel axle and segments.

A is thefront sill; B, the rear sill; G, D, and It, respectively, theouter, middle, and inner trusses which connect the front and rear sills.

F and G are respectively the outer and inner segments.

K is the drive'wheel axle; L, the raising and lowering pinions thereon.

c d e are the lower bars of the trusses O, D,

and E, respectively. 0, d, and e are the upper bars of the said trusses,respectively.

The segments F and G are secured, respectively, to the trusses O and 1),serving as struts for the same. The lower bars, d and e, of the trussesD and E are tied together at thelower end of the inner segment, (l, bythe crossbar H, and from the upper end of the segment G to the inner endof the bar H is extended the brace I, which is made fast at the upperend to the segment and at the lower end to the bar H and to the lowerbar, 0, of the truss E. This latter connection is almost directly in avertical line with the crest of the upper bent bar, 6, of the truss E,and near this point the upper and lower bars, 6' and e, are rigidlyconnected by the rod J, which is inserted through both bars and providedwith jam-nuts on both sides of each bar, thusforming a strut for thetruss E.

The purpose of this structure is to prevent the sagging of the segment Gin either direction. The triangle formed by the segment G, thehorizontal bar H, and the diagonal brace I, resting its inner angle uponthe bar e, and said bar being tied to the bent upper bar, 0,

- of the truss E, the benefit of the vertical rigidity of the truss isobtained, to prevent the drooping or sagging of the said grainward (Nomodel.)

angle of the triangle G H I; hence, to prevent the segment G fromleaning grainward, and the bar II being made fast to the bar 6, thesegment G is by the same means prevented also from leaningstubbleward-th at is, toward the wheel.

The segments G and F are held at uniform and nnvaryingdistance apart bymeans of the axle K and the pinions L L, made fast thereon. Saidpinions, meshing in the racks F and G on the segments F and G, areshrouded at both edges, so that they engage the racks laterally, wherebythe racks, and hence the entire segments, are prevented from lateraldisplacement relative to the pi nions. By this means the benefit of thedescribed bracing pro vided for the segment G is extended to the segment1?.

In thejoint application of Herman N. Kennedy, Burr A. Kennedy, andmyself, filed Oe tober 19, 1886, Serial No. 180,261, there is -shown theinner segment braced by rods extending from its upper end tothe frontand rear sills, and the pinions on the drivewheel axle doubly shroudedand engaging racks of the segment respectively; but said construction isnot therein claimed, it being my sole invention.

I claim- 1. In combination with the front and rear sills and the trussesD and E, connecting them on the grain side of the wheel, the segment G,secured to the truss I), the rod J, strutting the truss E, the cross-barH, and the brace I, united and operating substantially as and for thepurpose set forth.

2. In combination with the front. and rear sills and the truss D,connecting them on the grain side of the wheel, the inner segmentscoured to said truss, and a brace connecting the upper part of saidsegment with a fixed part of the harvester-frame grain ward thereof, andthe drive-wheel axle and the raising and lowering pinions made fastthereon and engaging the segment-racks and shrouded on both sidesthereof, substantially as set forth.

In testimony whereof I have hereunto set my hand, this 21stday ofAugust, A. D. 1886, in the presence of two witnesses.

JOHN F. STEWARD.
